Sing Sandwich cutaway exposing patented Sing CorePatented Sing Core is bringing the latest development in lightweight and high strength technology to visit the cabinet industry. Imagine being able to use a lightweight building material that is commensurate with high-tech aerospace technology at 20 percent of the price.

This new cabinetry alternative to MDF 4×8 sheets delivers many times the strength of solid MDF at a fraction of the weight with no headaches. Sing MDF cabinetry panels come in 4×8 and 5×12 sizes in convenient 3/4 inch thickness.

How are 3/4 inch Sing cabinetry panels made?

Start with patented Sing torsion box (2×3 inch grid size) where the voids are filled with recycled rigid foam insulation wall to wall with and sandwich it all between two sheets of 1/8 inch MDF and bond it altogether with formaldehyde-free adhesives for an Eco-friendly lightweight high strength composite MDF panels that out performs any other lightweight building material in terms of strength, weight and longevity.

Compare to other lightweight panel material

Compared to any other lightweight panel building material, like honeycomb panels made of paper honeycomb, aluminum honeycomb, cardboard, or even high-tech aerospace panels (costing five times as much per sheet) Sing 3/4 inch cabinetry panels are a bargain at twice the price.

Secret Ingredient Inside

High precision lightweight high strength warp resistant insulated reinforced torsion box Sing Core high performanceThe secret ingredient inside the Sing 3/4 inch cabinetry panels is the torsion box composite core that is the same product used by the US Navy and other high tech industrial applications where strength and weight are both considerations. This is the same technology used to build large doors – of any size or style – that can be guaranteed not to warp, bend, twist or otherwise fail for a full 50- years.

Imagine having this material inside your cabinetry and/or furniture… Say, “goodbye,” to disposable furniture and heavy cabinetry which are highly desirable qualities sought in aircraft, marine and recreational vehicle platforms for both less weight and less maintenance over time.

Even though plywood and particleboard are fairly standard fare in cabinet shops around the world, certain high end cabinet makers are seeking to embrace this new technology which is the perfect combination of old (torsion box) and new (composite) fine woodworking craftsmanship. Plus (as you undoubtedly already know) both plywood and particle board are heavy and prone to warp and rot; unlike Sing 3/4 inch torsion box cabinetry panels.

Structural integrity

The structural integrity of these hybrid cabinetry panels surpasses anything know in the affordable lightweight composite material and is increasingly finding its place amongst the transportation and general construction categories as an impressive upgrade alternative to plywood or other materials.

Built-in insulation

Sing composite cabinetry panels feature built in insulation (the rigid foam insulation filling the torsion box voids) that is a unique added feature whether you are building cabinets and/or other furniture.

Easy to work with

Standard woodworking tools are all that is required to take full advantage of Sing cabinetry panels, treat them just like you would any standard 4×8 piece of 3/4 inch panel.
Sing cabinetry panels are revolutionizing the industry as they are increasingly being found as a standard commodity in cabinet shops, millworks and furniture manufacturers throughout the United States and the world.


Sing cabinetry panels have unfinished (exposed, i.e. you can see the core) edges. This is easily remedied by adding edge trim, or closing the edge by any method desired. Also, the core material can easily be routered to accommodate insertion of wood implants where desired or necessary.

Simply CNC router out Sing Cabinetry Panels to insert any desired material.

Kitchen Cabinets Non Warping Custom Cabinets

Lowes kitchen cabinets torsion box panel countertops cabinet substrateHere, at Sing Core, we have staff dedicated to solving the problems associated with high end custom cabinets, butcher block island, kitchen island table and wood furniture for the best clients. For the masses, cheap kitchen cabinets work fine due to their standardized sizes not requiring much continuous material. The problems associated with kitchen cabinets do not become apparent until you start to play with the dimensions and increasing the raw material.

The most exquisite cabinet makers know how to make cabinet doors that will not warp, bend, twist or fail – up to a point. Once the door sizing gets to a certain threshold, you will begin to have problems associated with a warped cabinet door.

Lowes knotty alder kitchen cabinetsFor the most part, cabinet shops specializing in custom cabinets do not see these extreme sizes except for in very exclusive contemporary interior designs and the large size is both elegant and impressive. As beautiful as these large luxury kitchen cabinets can be, having tall cabinet door warp is not a good thing for the client and does not reflect well upon the cabinet maker.

The same is true for any unsupported span of raw material in cabinet doors, large kitchen island tables or wood furnishings. At some point, the material itself will lead to failure due to warping wood or other building material. Many materials have been used in an attempt to prevent warping kitchen cabinets, like melamine, laminate cabinets, MDF cabinets, plywood cabinet doors and even resorting to aluminum cabinet doors to address the warped cabinet door issue.

Solid Wood Cabinets

By far the most popular high end clients prefer the look and feel of solid wood cabinets. Of the many wood species that are trending in growing popularity include:

  4. Cherry wood cabinets
  5. Knotty pine cabinets
  6. Pine cabinets
  7. Walnut kitchen cabinets
  8. Bamboo kitchen cabinets
  9. Birch cabinet doors
  10. Teak cabinet doors

In most cases, solid wood cabinets function well over a period of time, if they are of standard size. If your custom cabinets are rather large and include large spans of solid wood, it will bend, warp or twist; such is the nature inherit with the natural grain in the wood fiber.
